Buggered if I know. There is no point trying to time short term fluctuations (there is a half-decent stab at explaining why here)
Brexit innit? Free Trade might be the ideal situation in theory, but the costs of transition to such a situation are ignored in the theory and unknown (but potentially vast) in reality. Jacob, Boris and Theresa would have you appreciate all they are doing for you though.
You have my sympathy. We are wrestling with when or if to repatriate a sizable chunk of Euros. It is giving me nightmares as it is all my money and the fluctuations are driving me nuts. I would buy a Villa in Spain but the Catalonians aren’t doing enough to drive down Valencian property prices, the selfish feckers.
